Compare cell phone plans and find the perfect plan to fit your usage needs at web site BillShrink. Just enter some information about how you use your phone along with your current monthly bills, and BillShrink will offer you an alternative plan that could save you a ton of cash. Currently BillShrink is focused on cell plans only, but they appear to be working towards offering more comparisons for cable and internet bills in the future. BillShrink doesn't take phone availability into account, so if you want an iPhone, for example, you're stuck with AT&T (unless you unlock it). Let's hear if BillShrink helped you find a better plan in the comments.
